IMPERIAL

PATENT OFFICE.

The invention relates to a floor setting device for elevators.

The construction described below

combines the advantage of a high parking speed for the accuracy of elevators of stopping, at the same time with a very compact assembly.

An embodiment of the subject matter of the invention is shown in FIG. The drum shaft ι is extended and carries the axially displaceable by means of annular grooves Drive plates 2, 3, 4, etc., the pins 5 of which are used for parking. These pins 5 can on the circumference of the disks 2,3,4 by means of a dovetail groove or a similar one Device can be set as desired and then fastened. The drive plates 2, 3, 4 are prevented from twisting the shaft by means of a tongue and groove, so that they can only make axial movements on the shaft. In a bracket 6, which swings freely around the drum shaft 1, is a threaded spindle 7 rotatably mounted. The same is used to move a nut 8, which is supported in the lower part against the bracket 6 and guided through the same is, but is formed in the upper part as a nose that with the pins 5 with the drum shaft ι rotating driver plates 2, 3.4 can meet. The bracket 6 is up by suitable means in a fixed connection, both with control cable 9 that goes through the floors goes, as well as with the shaft 10, which the parking device on the elevator machine influenced.

In order to make it possible that only a certain driver with the wandering nose the same meets, the thread pitch of the spindle 7 is dimensioned so that the: Nut covers more distance than the thickness of the pin 5 during one drive rotation amounts to. It is therefore possible to use the drive plates and the ones that can be moved on them Adjust the pins opposite the position of the nut 8 "so that the nose of the nut is free can go through. This is the basic position ^ in which no floor is set.

The driver belonging to any stop can now be used in the following way Meeting with the nose of the mother 8 are brought. - The drive plates 2, 3, 4 are each axially displaceable by a small amount on the drum shaft 1, in such a way that if one driver is moved, the others are still in their old position remain and that only when the previously moved driver in its original The position has returned, another driver can be moved, etc. This is made possible by swinging around the fixed points 11 double levers 12, 13, 14, which with engage the lower end in the grooves of the driver 2,3,4, but with the upper end, under influence; of springs 15, themselves support against a rod 16, which the to the corresponding levers 12, 13, 14, belong Projections 17, 18, 19 carries with a suitable mutual spacing. The postponement the rod 16 takes place from the floors by means of adjusting rope 20, pulley 21 and

Claims (3)

Gear 22, which the latter engages directly in the rod 16 designed as a rack at the end. The projections 17, 18, 19 and the levers 12, 13, 14 with their drivers 2, 3, 4 and their lugs 5 can be adjusted as required in order to fit every floor height. If the elevator should now go from any floor to another, in Fig. 1 z. B. in the floor 3, the adjustment rope 20 is set to the mark of the floor 3 on any floor, whereby the driver 3 is brought with its nose 5 from the dotted old position in the new position shown. The control cable 9 is then pulled up, whereby the elevator machine is started by means of the shaft 10 and the bracket 6 is rotated from its central position in a direction opposite to the direction of rotation of the shaft 1 that is now beginning. The switch nut 8 now moves when the machine is running z. B. from left to right and happens first the driver 2 BEZW. its nose 5, without meeting the latter, because 2 has remained in its old position. When you go on but now the switch nut 8 comes in the area of the set driver 3 respectively. whose pin 5. Pin 5 couples nut 8 and bracket 6 to the drum shaft 1 and thereby pulls the control back into the rest position. In order to move to another floor, nut 8 and pin 5 are decoupled by the axial displacement described above and another driver 2 or 4 belonging to the desired floor is placed in the path of the switching nut 8 by axial movement. The principle of construction with its advantages for accuracy can also be transferred to electric elevators with push-button control. According to FIG. 2, an off switch 25 is placed on the switching nut, which is hit by the pins 5 of the drive plates and interrupts the auxiliary circuit, whereby the elevator is switched off. In order to avoid the adjustment rope, the disks 26, 27, 28 are arranged so that each of them hits the switch on its way; However, in order to obtain a power interruption only for the pane of the desired floor, care is taken that the circuit breaker is only traversed by the current shortly before the pane in question. For this purpose, the nut 29 moves a rail 30 firmly connected to it in correspondingly insulated guides. Metal strips 31532, 33 are attached to the rail 30 and separated by two insulating pieces 34, 35. 37, 38, 39 are fixed contacts, each of which belongs to a floor and which are in contact with the strips 31, 32, 33. The strips 31 and 32 are connected by a line 36; A line 41 is connected to 33 and leads to the circuit breaker 25, from which a line 42 goes to the rail 32. The insulating pieces 34, 35 are made significantly narrower than the contacts 37, 38, 39 in order to avoid a current interruption at the transition. The floor contacts 37, 38, 39 receive current from any known floor switch in such a way that after pressing a button the auxiliary current goes through the relevant floor contact during the entire journey, the auxiliary current being connected to the starter in such a way that an interruption causing the machine to stop. Is now z. B. the switching nut 29 on the right outside of the spindle and the contact 38 of the middle floor is supplied with power, this continues through rail 31, line 36, rail 32, line 40 until the nut moving against contact 38 while driving has come far that the contact 38 begins to cover the insulation point 34 and so the current partly through line 36, partly through line 41, the circuit breaker 25 and line 42 to the rail 32 continues. Finally, if contact 38 only touches the strip 33, all of the current goes through the circuit breaker. At this moment the elevator must be in the correct position, pin 5 must hit the switch, the current is interrupted and this causes it to be switched off. While the mother was walking in, the off switch was also opened by the pin of the disk 28, but this was ineffective because it had no power at all. The process proceeds in the same way if any other floor contact receives power. Godfather nt-A ν Proverbs: 1. A floor setting device for elevators, characterized in that two parallel shafts both have a rotary motion dependent on the elevator's drive mechanism obtained, one being designed as a screw spindle on which a nut with a nose moves, while the other carries a pegged disk for each stop so that the appropriate one goes through Immediate meeting of pen and nose, the stop of the elevator is effected. 2. An embodiment of the device according to claim 1, for mechanical, hydraulic or electric elevators, characterized in that the individual Floors belonging to the drive plates can be moved axially from each floor in such a way that that only the drive plate that belongs to the set floor with the passing nose of the mother meets (Fig. i). 3. An embodiment of the device according to claim 1 for electrical on Trains with push-button control, characterized in that the at the circulating Drive plate moving nose belongs to a switch that is hit by every drive, but only shortly before the elevator arrives at the certain floor of the auxiliary stream is traversed, so that only that caused by the associated driver Opening the switch causes the power to be interrupted and the elevator to stop (Fig. 2). 1 sheet of drawings.
